Splinter cell: Blacklist
Main missions are fun but the side missions, most of which seem to involve not being seen can be very frustrating when 1 mistake sets you back to the beginning. I was sneaking on a yacht, made my though quite a bit of it, opened a door to find I was in a hallway full of lazer of beams. Great, thanks game, not like it took 30 mins to get here, sure I don't mind starting from scratch.
